The complex of oat β-glucan (OBG) and flavonoids hampered the digestion of starch-based food and retarded the blood glucose response; however, its effect on gastric emptying and its relative mechanism have not been thoroughly investigated. By using Fourier transform infrared (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), antioxidant ability, and enzymic inhibitory tests for the characterization and in vitro semi-dynamic digestion of complexes of OBG (high and low molecular weights) and sea buckthorn flavonoids, we found that the higher molecular weight complex (FU) exhibited stronger ABTS and DPPH radical scavenging abilities and higher α-glucosidase and α-amylase inhibition rates. Mice fed with rice flour with FU addition exhibited the slowest gastric emptying and intestinal propulsion rates and blood glucose rise and had the lowest activity of digestive enzymes and levels of insulin, ghrelin, motilin (MTL), and relevant gene (ghrelin and GHSR mRNA) expression than those in the control and low-molecular-weight groups. This study provided scientific data for the development of foods with delayed gastric rate and hypoglycemic index for specific populations.

ABSTRACT The non-thermal and thermal effects on aroma of sea buckthorn juice have rarely been investigated. In this study, 57 odor compounds were identified in fresh sea buckthorn juice (FSBJ), high pressure processing sea buckthorn juice (HSBJ), and pasteurized sea buckthorn juice (PSBJ), including 29 esters, 8 aldehydes, 1 ketone, 5 alcohols, 5 acids, 6 terpenoids, and 3 others. Ethyl 2-methylbutanoate, ethyl 3-methylbutanoate, ethyl hexanoate, and ethyl 2-hydroxy-3-methylbutanoate with flavor dilution factors ranging from 729 to 59049 contributed to the fruity odors of FSBJ and HSBJ. Besides, the formation of off-odor compounds including hexanal, nonanal, furfural, 3-methylbutanoic acid, and dimethyl disulfide with odor activity values ≥ 1, imparts fatty, roasted, sweaty, and cooked odor in PSBJ. The variations of vitamin C and reducing sugar are significantly associated with changes in odor-active compounds during pasteurized processing. These findings provide new insights that high pressure processing minimizes the adverse effects of pasteurization.

Epoxy resin (EP) is a versatile material widely used in fields such as electronic encapsulation, coatings, adhesives, and composites. The targeted assembly of nanomaterials to optimize the flame retardancy, mechanical properties, and interfacial properties of composite materials is a prominent research hotspot in the field of EP. Therefore, a hierarchical sea-urchin inspired architecture (NiPS@LDH), based on layered double hydroxide (LDH) nanosheets grown on nickel phyllosilicate (NiPS), was rationally constructed as a functional filler for EP with a view to building high-performance EP composites. The addition of 1 wt% NiPS@LDH increased the tensile strength, modulus of elasticity, and elongation at break of EP by 44.1 %, 27.6 %, and 66.2 %, respectively, showing excellent strengthening and toughening effects. Meanwhile, under dry friction conditions, the wear rate of the composites was 0.86 mm 3 ·N −1 ·m −1 , reduced by 87.8 % compared to that of pure EP, indicating excellent wear resistance. Besides, the pHRR, THR, pSPR, TSP, pCO and pCO₂ of EP/NiPS@LDH-3 composites were found to be significantly reduced by 54.0 %, 61.9 %, 50.7 %, 54.4 %, 51.2 %, and 58.2 %, respectively. The LOI value of the composites increased to 26.4 %, and the maximum weight loss (R max ) was reduced by 27.7 %. This study provides an innovative strategy for the targeted assembly of nanomaterials, paving the way for the preparation of high-performance EP nanocomposites.

In this study, tannin-derived porous carbon (TAC) with different microstructures was prepared via a microwave hydrothermal method, followed by KOH activation. Subsequently, the sea urchin–like NiCo-LDH/Tannin-derived carbon-based microsphere composite materials were rationally synthesized through a single-step microwave hydrothermal co-assembly process. The physicochemical characteristics and supercapacitive performance were systematically analyzed. TAC with a microspherical structure promoted and controlled the growth of LDHs, resulting in a more regular sea urchin–like structure, improved dispersibility, reduced resistance, and increased active sites. NiCo-LDH@TAC600-0 (without KOH activation) as an electrode material delivered a specific capacitance (Cs) of 1250 F g −1 at 1 A g −1 and 1035 F g −1 at 10 A g −1 , with a rate performance of 82.8%. The asymmetric supercapacitor device using NiCo-LDH@TAC600-0 and TAC provided an energy density of 30.8 Wh kg −1 at 800 W kg −1 and a capacitance retention rate of 72.5% after 5000 cycles. This study offers a novel approach to enhancing NiCo-LDH properties for efficient energy storage.

Transition metal phosphides (TMPs) have emerged as promising high-capacity anode materials for lithium-ion batteries (LIBs). However, their practical application remains constrained by the dual challenges of intrinsic low conductivity and structural degradation during cycling. In this study, CoP/C composites with hollow spherical (denoted as s-CoP/C) and sea urchin-like (u-CoP/C) morphologies were synthesized in a morphology-controlled manner using sodium citrate as a structure directing agent, aiming to elucidate the structure-performance relationship in lithium storage. Systematic characterization reveals the hollow spherical architecture of s-CoP/C effectively enhances charge transfer kinetics and buffered volume variations during cycling, outperforming its u-CoP/C counterpart. As a result, s-CoP/C delivered a stable reversible specific capacity of 527.5 mAh g −1 after 600 cycles at 1 A g −1 . Kinetic analysis demonstrates a dominant pseudocapacitive contributes of 85.6 % at a sweep rate of 1.5 mV s −1 . In addition, robust interfacial chemical bonding between CoP and carbon matrix through C–P and Co– O –C linkages ensures structural integrity during prolonged cycling. This work establishes a synergistic strategy combining morphological engineering with interfacial optimization to develop durable TMP-based anodes for advanced energy storage systems.

Sea buckthorn is rich in active ingredients, widespread, and has both medicinal and nutritional value. The present comparative study of wild and cultivated species remains insufficient, which is not conducive to their quality control. Therefore, this study aimed to compare the differences of 21 sea buckthorn samples in total phenolic content (TPC), total flavonoid content (TFC), phenolic components content, secondary metabolites, and antioxidant capacity and the fatty acid, to investigate the quality differences of different varieties. The TPC, TFC and antioxidant activity of wild varieties were higher than those of the cultivated. Multivariate statistical analysis revealed large differences in phenolic content, with higher levels of gallic acid and isorhamnetin-3- O -neohesperidin in the wild, whereas the cultivated were characterized by narcissin and kaempferol. These findings provided the scientific basis for the improvement of quality evaluation standards for different varieties and offered new insights for the further development of sea buckthorn resources.

Salt enhances flavor and salinity in Chinese curing; however, excessive use can pose health risks, while reducing NaCl may harm taste. This study utilized targeted and untargeted metabolomics to investigate the intrinsic molecular mechanisms that drive flavor formation in cured sea bass subjected to salt. Glycine, succinic acid, lactic acid and uridine significantly contributed to the taste profile of the cured sea bass. A total of 668 lipid molecules were annotated in the samples, of which 60 were classified as differential lipids. Non-targeted lipidomic analysis identified phosphatidylcholine and phosphatidylethanolamine as the major flavor precursors, constituting 40.12 % of the total. Elevated salt concentrations significantly enhanced the production and accumulation of key differential volatile flavor components, including 1-octen-3-ol, 2-undecanone and 2-pentylfuran. Thus, salt facilitated the degradation and oxidation of lipids, leading to the formation of key flavor compounds that contribute to the enhancement of the flavor profile of cured sea bass.

Bivalves (Mollusca: Bivalvia) are an important source of animal protein for coastal communities. Given bivalves are typically stored at room conditions for a period to eliminate sand and undergo depuration before reaching consumers. Evaluation of the nutritional composition and contaminant levels in bivalves available in the markets can serve as an indicator of the quality of bivalves reaching consumers. In this context, this study assessed the protein and lipid nutritional quality, as well as non-essential trace metal content, of three commercially available bivalves ( Anadara granosa (cockles), Meretrix meretrix (clam), and Crassostrea hongkongesnsis (oyster)) from the Maowei Sea, China. The findings of this study can provide consumers with clearer information on the nutritional quality and contaminant levels of market-sold bivalves from this region.

Ready-to-eat sea cucumbers (RSC) cannot be preserved at room temperature due to autolysis, which is closely related to the instability of collagen resulting from the disruption of hydrogen bonds. To investigate the protective effect ofN-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride/N-hydroxysuccinimide (EDC/NHS) cross-linking against disruption of hydrogen bonds and its role in stabilizing RSC quality at room temperature, this study designed comparative experiments involving EDC/NHS cross-linking treatments with varying sequences of hydrogen bonds disruption. The results indicated that EDC/NHS positively affects the stabilization of the collagen structure in RSC. The various quality parameters of both groups of RSC that underwent cross-linking treatment before and after hydrogen bonds disruption were significantly better than those of the control group, which only experienced the breaking of hydrogen bonds. Notably, the Eb group, which underwent EDC/NHS cross-linking treatment prior to the disruption of the hydrogen bonds network, yielded even more favorable results. Preliminary analyses of textural properties and moisture content suggested that EDC/NHS helps delay the deterioration of RSC quality. The levels of soluble components and carbonyl groups indicated that prior cross-linking treatment is more effective in mitigating collagen degradation and oxidation. Differential scanning calorimetry revealed that the reduction in ΔH for the Eb group was only 2.4%. Furthermore, fluorescence spectroscopy, Fourier transform infrared spectroscopy, and circular dichroism spectroscopy, examined from the perspectives of secondary and tertiary structures respectively, indicated that the cross-linking mechanism of EDC/NHS involves the formation of a more robust network of amide bonds, thereby preventing the disruption of hydrogen bonds and enhancing collagen stability, enabling it to better resist the cleavage of hydrogen bonds due to urea. The scanning electron microscope and Van Gieson’s staining techniques offer a clearer illustration of this point from a microscopic perspective. Moreover, molecular docking simulations have indicated the cross-linking mechanism of EDC/NHS at the atomic level, thereby establishing a scientific foundation for the potential application and development of EDC/NHS in room-temperature storage technologies for RSC.

Simultaneously addressing global freshwater and energy resource scarcities demands the development of advanced multifunctional materials. However, integrating solar-driven desalination with the selective extraction of strategic resources like uranium in a single, durable platform remains a significant challenge due to functional interference and heat loss issues. Here, we report a Dragon Blood Tree-inspired bilayer evaporator (PCZC) constructed from a PPy@CF photothermal layer and a ZnO@CF adsorption layer, vertically supported by a cotton fiber “stem.” This unique “crown-stem” bionic architecture mimics the functional compartmentalization of Dracaena cinnabari , elevating the functional layers from the bulk water to minimize conductive heat loss while enabling directional transport of water, ions, and vapor. The resulting evaporator exhibits remarkable multifunctionality: it achieves a high solar evaporation efficiency of 98.0% at 7-day average evaporation rate of 1.64 kg m −2 h −1 , and for resource recovery, it attains a uranium adsorption capacity of 7.63 mg g −1 , which remains stable over 5 consecutive days of solar-driven operation. Furthermore, it demonstrates an significant uranium desorption efficiency of 87.5% and a high salt recovery rate of 100.64 g m −2 h −1 . The spatial partitioning of the crown-stem structure not only prevents cross-contamination and surface fouling but also enhances the system's operational durability. This work offers a novel biomimetic strategy based on “structural cooperation” to construct multifunctional platforms, presenting a promising candidate for sustainable and comprehensive seawater resource utilization.

Organic coatings are ideal candidates for mitigating corrosion and mechanical wear of metal-based substrates due to the effective physical barrier capacity in marine environments. However, their performance is often compromised by inherent defects, alternating hydrostatic pressure (AHP), and mechanical wear, ultimately resulting in coating failure and substrate corrosion. This study presented a high-performance composite coating by integrating core-shell nanohybrids (GO@pPTFE) into waterborne epoxy resin matrix. The combination of low surface energy PTFE core and GO nanosheets featuring abundant functional groups not only balanced high hydrophobicity and strong adhesion but also endowed the coating with outstanding corrosion resistance (|Z| 0.01 Hz value of 8.7 × 10 9 Ω·cm 2 even after 30 cycle of immersion under 20 MPa AHP environment). Furthermore, the resulting coating exhibited stable low coefficient of friction (0.027), excellent anti-wear property (wear rate of 0.96 × 10 −6 mm 3 ·N −1 ·m −1 ), narrow wear track width (195 μm), and slight wear tracks. These significant improvements were mainly ascribed to the robust interfacial adhesion, effective barrier properties, robust interfacial adhesion, and synergistic wear reduction effects associated with the constructed GO@pPTFE core-shell nanohybrids, making the coating a promising strategy for deep-sea corrosion and wear challenges.

Free amino acids (FAAs) are key organic nitrogen (ON) components in marine aerosols, revealing aerosol sources, transformation processes, and potential impacts over oceanic regions. Total suspended particle samples were collected during four cruise campaigns (2013–2016) over the South China Sea (SCS) to investigate FAAs in marine aerosols. The average concentrations of the total FAAs (TFAAs) ranged from 8.06 to 29.77 ng m–3 in the four campaigns, reflecting the continental influences from the Indo-China Peninsula (ICP) and East Asia (EA). The ICP-influenced samples were predominantly influenced by relatively fresh biomass burning emissions, whereas the EA-influenced samples reflected a mixture of biomass burning and photochemical formation processes. Glycine (Gly) is the major FAA species, accounting for 47.9–64.1% of TFAAs. We estimated the contributions from photochemical degradation and biomass burning to Gly in EA-influenced samples based on Gly/TFAA ratios and correlations between FAAs and continental tracers and found that photochemical degradation significantly enhanced Gly accumulation in continental outflows from EA. This process delivers highly bioavailable ON, with EA-influenced air masses bringing about 10 times higher ON loadings to the SCS atmosphere compared to ICP. This highlights the importance of long-range transport and atmospheric oxidation for SCS nitrogen deposition ecological impact.
